Composite Bearings, Slider Precision Bearing Supplier

Self-lubricating bearings are a metal-backed system with multiple lining options to optimize a solution for your unique applications.

Featuring a unique polymer liner that is sintered to a porous bronze interlayer. Plain bearings sliding bushings are self-lubricating and can withstand the most rigorous of working environments. We can easily manage high-loads and excessive speeds and can protect your machinery in the rare instance of a liner wear-thru since the supporting interlayer is also self-lubricating.

Whether your job calls for standard or metric dimensions or requires steel, zinc, or copper-plated backing, Bronzelube has you covered. We’ll help you match the right material to enhance product wear life by evaluating the speed, load, temperature, and lubrication of your hardware. And we’ll do it all at a competitive value.

Self-lubricating bearings work by having lubricant impregnated within the sliding layer of the bearing. This lubricant can either be liquid (oil) or solid (PTFE, POM Layer, graphite, MoS2, lead) based on the requirements of the application (such as operating temperature). As the sliding bearing operates, the lubricant is released through pores in the sliding layer, lubricating the bearing surface.

What are self-lubricating bearings?

Self-lubricating bearings, as the name suggests, provide their own lubrication during operation, without the need to apply grease or lubricating oil.

For this reason, self-lubricating bearings are also referred to as maintenance-free or grease-free bearings because they do not require relubrication or lubrication.

Wear rate and operation under specific loads, temperatures and speeds are all important considerations when choosing the best bearing for your application. The effects of dust, dirt, or chemicals on the bearing are also often deciding factors, as are noise levels and performance with different shaft materials.

How important are self-lubricating bearings in the aerospace industry?

The aerospace industry needs low friction bearings with excellent wear resistance to reduce labor costs. In addition, many areas of an aircraft are difficult to access for servicing and therefore benefit from components with long service life, namely self-lubricating bearings.

Self-lubricating bearings eliminate the need for maintenance, reduce labor costs, and extend life in aerospace applications.

Self Lubricating Bronze Bearings With Solid Lubricant

Self-lubricating bronze bearings are maintenance-free due to the fact that they are manufactured with solid lubricating materials, such as graphite inserts.

They are particularly suitable for applications where manual lubrication is difficult or where oil and grease lubricants cannot be used. They provide excellent lubrication at high loads and slow speeds.

We manufacture all our self-lubricating bronze bearings based on clients’ designs.
